Vwhich the followino` is a specification.

This invention relates to stand valve ball lift attachments adapted to be applied to the lower ends of working barrels in oil wells and it consists in the novel features hereinafter described and claimed.

By the use of the invention hereinafter described the tubing which is generally employed in an oil well may be positioned upon the bottom of the well and the working barrel may be located therein. `The attachment includes a ball-cage which is mounted at the lower end of the working barrel, there being means provided for lifting the ball in the cage when it is desired to remove the barrel from the tubing in order to permit the oil which is above the cage to drain back in the Well and thus prevent loss. It is kthe present practice when removing the barrel from the well to lift the oil which is above the valve of the barrel out of the tubing as the barrel is moved toward the upper end of the tubing.

This oil is wasted at the upper end ofthe tubing and the waste amounts approximately to two barrels of oil to every one thousand feet of tubing. By employing the present invention this waste is avoided.

In the accompanying drawing Figure 1 is a fragmentary sectional view of the working barrel with the attachment applied.

Fig. 2 is a longitudinal sectional view-of the same.

Fig. 3 is a similar view showing the parts iid different positions from those shown in Fig. 4 is a side elevation of a rod used in the attachment. f

Fig. 5 is a transverse sectional view of the attachment.

As illustrated in the accompanying draw-y ing the workingbarrel is indicated at 1 and a packing block 2 is attached to the lower end. thereof. A valve cage 3 is centrally positioned `in the packing block 2 and carries a ball valve 4 of usual pattern. A pipen is specification of mee/Patent. Patented A119217., 1.9.18-

attached at its upper end to the block2 and is provided at its sides with suitable openings 6. A washer-7 is inserted in the lower end of the pipe 5. A rod8 passes centrally through the washer 7 and moves longitudinally through the same- A spacing disk 9 is screwed upon the rod 8 and is inclosed within the pipe 5. The said disk 9 is provided with a serrated periphery 10 which forms passageways for the movement of the oil.:

A jam nut 11 is screwed upon the. rod 8 and bears against the upper face of the disk 9 whereby the said disk is held at an adjusted position upon the rod 8. The said rod 8 is provided at its upper end with a long thin point 12. This point at times is adapted to enter the cage 3 and move the valve 4 away from its seat in the cage. A

tube 13 surrounds the lower portion of the v rod 8 and the lower end of the said tube projects below the lower end of the said rod. The tube 13 carries at its upper end a washer 14 which is screwed upon the rod 8. VA nut 15 is also screwed upon the rod 8 and bears against the under face of the washer 14 whereby the said washer is held at an ad-Y justed position upon the rod 8. Y

Under normal conditions the lower face of the disk rests upon the upper surface of the washer 7. Vhen it is desired to remove the barrel from the Vwell without wasting the oil the barrel is lowered so that the lower end of the tube 18 comes in contact kwith the bottomV of the well and the rod 8 From the foregoing description taken iny oonjimction with the accompanying drawing it will be seen that a ball valve lift device of simple and durable structure isA provided and that the same may be used to advantage for preventing the waste of oil when it is necessary to remove the working barrel from the' tubing of a well.

Having described the invention What is Claimed is zf A valve lift comprising a packing, a cage mounted on the packing, a ball valve located in the cage, a pipe attached to the cage and provided with openings, a rod Inovably mounted in the pipe and having a pointed end adapted to enter the cage and niovethe ball from its seat, a serrated disk mounted upon the rod and located Within the pipe, means for locking the serrated disk at an adjusted position upon the rod, a tube mounted upon the rod at a point below the pipe and means for' securing the tube at an adjusted position upon the rod.

In testimony whereof I ax my signature.
